is he cheating on me???

[Blue]

Ok, i'm not themost confident of guys. I constantly suspect my boyfriend of cheating

Are you this way with anyone or is it you lack of trust in him only that's causing this?

he is a really horny guy who is known for being promiscuous and has had hundreds of one night stands

Probably wise to be suspicious if that's his reputation.

i created an account on gayder, jealously and proceeded to add a picture of an attractive guy from the internet on to the account. i messaged him and asked him how he was, what he was looking for (he replied that he was just going with the flow and not looking for anything in particular but was open tn things), i asked him when was the last time he had had sex and he said, not until last week, (bear in mind, i had left the country 3 weeks at this stage), i then revealed myself to be myself on the account and he said, that he knew it was either me or some other guy, that he only said that he had met someone a week ago to find out if it was me and knew i would reveal myself, that he thought it was suspicious that a new account with no views would message him out of the blue, and whatnot. he also said he expected me to do this for a while as i am an insecure and untrusting guy.

Whoa, hold it, stop right there. This is playing head game, and that is never good.

Both of you need to stop this immature B.S. and talk openly and honestly regardless of it you think it will hurt the other's feelings or, even if you think the other might break up with you for saying and asking what you need to say and ask. Just be honest and demand the same of him, figure out where you want your relationship to be and, what you expect and need from each other, and go from there to decide what will be best for you both in the long term.
